Developed by Koreans for the Japanese, Boong-Ga Boong-Ga is the first arcade game that combines of assaulting assholes and fortune-telling. You select from eight characters like "Mother-in-Law," "Con artist," and "Child Molester" and then, steel yourself for this, you ram a giant plastic finger into an ass that protrudes out from the arcade unit next to the words "HAVE A FUN!! ENJOY." As you poke, spank, and probe, the game plays an animation of your victim wailing in pain, and then the game, and I'm not fucking kidding, rates your sexual virility based on the impact of your finger against its virtual colon. Oh, and its corporate mascot is a six foot magical monster made out of turd. (see below for the revealing brochure)
